What 40840 covers

This procedure deepens the anterior vestibule by releasing and repositioning soft tissue, creating more space between the lip or cheek and the alveolar ridge. Oral and maxillofacial surgeons commonly perform it for a shallow or tethered anterior vestibule when reconstruction is needed, including in patients with an inadequate denture-bearing area. It is generally performed in a surgical setting, with the operative report identifying the treated site and extent of reconstruction.

Choose this code for anterior vestibuloplasty; posterior procedures, reconstruction of the entire arch, or complex work including ridge extension belong to other codes in the family. Medicare payment is restricted to specific circumstances, so documentation should establish the clinical reason for reconstruction and describe the work performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and each other procedure is paid at 50%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

40840 billing questions

When should 40840 be selected instead of a posterior vestibuloplasty code?

Use 40840 for reconstruction of the anterior vestibule. Posterior procedures are reported with the applicable posterior code based on their site and extent.

Can modifier 50 be reported for bilateral anterior work?

No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.

What documentation supports reporting 40840?

Document the clinical need for anterior vestibular reconstruction, the specific site, and the operative steps and extent of tissue release or repositioning.

Does the global period include postoperative visits?

Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant surgeon be reported?

CMS permits payment for an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and each other procedure performed in the same session is paid at 50% under the standard multiple-procedure reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
